The U.S. government’s plan to vaccinate most Americans by next summer rests heavily on two COVID-19 shots that U.S. regulators won’t get a chance to rule on until early in 2021.
AstraZeneca Plc and Johnson & Johnson together would provide 150 million to 200 million shots in the first quarter, said Moncef Slaoui, chief scientific officer of Operation Warp Speed. This could immunize 110 million to 150 million people, if the doses are evenly split between J&J’s single-dose vaccine and Astra’s two-dose regimen.
